The Latest: Firefighting chemical found in Denver-area water

July 12, 2018

DENVER (AP) — The Latest on chemicals detected in suburban Denver drinking wells (all times local):

5:30 p.m.

A suburban Denver water utility says it has shut down three wells after potentially harmful chemicals used in firefighting foam and manufacturing were found in the water.

The South Adams County Water and Sanitation District said Thursday it is buying water from Denver’s utility to make up the difference. The Adams County district serves about 50,000 people in Commerce City.

The district says PFC compounds were detected in 12 wells with concentrations from 24 to 2,280 parts per trillion. The district says after treatment, the water had between 45 and 64 parts per trillion.

The federal government’s advisory limit for PFCs is 70 parts per trillion.

The district says it expects PFC levels in its treated water to decline now that some wells have been shut off and Denver water is being added.

PFCs have been linked to cancer and other illnesses. They are being phased out of some applications.

Low levels of potentially harmful chemicals used in firefighting foam and manufacturing have been found in suburban Denver drinking water wells.

The Colorado Department of Public Health and Environment said Thursday that compounds called PFCs were detected in wells used by the South Adams County Water and Sanitation District, which has about 50,000 customers in Commerce City.

The health department says the concentrations are below the federal government’s advisory limit. The water district says its water is safe.

Some kinds of PFCs have been linked to cancer and other illnesses.

The utility says its treatment plant is already removing some PFCs from the water. Officials say they’re increasing the amount of water they get from other sources.

Federal, state and local agencies are looking for the source of the PFCs.
